The next loop is the For loop. The idea of the for loop is to "iterate" through something. For each thing in that something, it will do a block of code. Most often, you will a for loop's structure very much like

for eachThing in thisThing:
   do this stuff
   in this block
So, again, why would someone use each type of loop?

Typically, you will see the while loop being used for finite tasks that have predetermined length, and the for loop being used for tasks that have uncertain and variable time-frames.

That said, the for loop can be used for the exact same tasks as the while loop.

For this reason, I prefer the for loop myself, but again, it comes down to personal preference.
